register_assert_handler(3alleg4) Allegro manual register_assert_handler(3alleg4)


register_assert_handler - Registers a custom handler for assert failures. Allegro game programming library.


#include <allegro.h>

void register_assert_handler(int (*handler)(const char *msg));


Supplies a custom handler function for dealing with assert failures. Your callback will be passed a formatted error message in ASCII, and should return non-zero if it has processed the error, or zero to continue with the default actions. You could use this to ignore assert failures, or to display the error messages on a graphics mode screen without aborting the program. You can call this function even when Allegro has not been initialised. Example:

int show_but_continue(const char *text)
alert("Uh oh...", "Fasten your seat belts.", text,
"&Go on!", NULL, 'g', 0);
return 1;
ASSERT(0); /* This won't crash the program now. */
